Alkylation reagent

In a typical experiment a portion of the 5 -labeled single-stranded DNA is reacted with dimethylsulfate under conditions where many but not all of the purine bases react. This reagent alkylates the N7 position... [Pg.246]

In the general context of donor/acceptor formulation, the carbonyl derivatives (especially ketones) are utilized as electron acceptors in a wide variety of reactions such as additions with Grignard reagents, alkyl metals, enolates (aldol condensation), hydroxide (Cannizzaro reaction), alkoxides (Meerwein-Pondorff-Verley reduction), thiolates, phenolates, etc. reduction to alcohols with lithium aluminum hydride, sodium borohydride, trialkyltin hydrides, etc. and cyloadditions with electron-rich olefins (Paterno-Buchi reaction), acetylenes, and dienes.46... [Pg.212]

One of the most common types of reactions carried out to prepare organic derivatives of the group IVA elements is that of transferring an alkyl group by means of a Grignard reagent. Alkylation of SnCl4 can be illustrated as follows ... [Pg.477]

The reaction of dialkylditellurides with pressurized acetylenes in the presence of an electrophilic reagent (alkyl halide, Lewis acid), in the system KOH/crown ether/ben-zene, gives rise to alkylethynyl tellurides and 1,2-bis-alkyltelluroacetylenes in high yields. ... [Pg.109]

By treating fluoronanotubes with strong nucleophiles such as Grignard reagents, alkyl- and aryllithium reagents, metal alkoxides, acyl peroxides, amines and diamines, the fluorine atoms can be replaced through substitution [29, 47-50]. [Pg.7]

Another method to generate sodium arenetellurolates for subsequent alkylation is the disproportionation of diaryl ditellurium in basic medium to arenetellurolates and arenetellurinates. When the disproportionation reactions arc carried out in the presence of a primary alkyl bromide or alkyl chloride and a dialkyldimethylammonium chloride as phase-transfer reagent, alkyl aryl telluriums are obtained in approximately 60% yield. [Pg.396]

Another factor affecting the nucleophilicity of these ions is their solvation, particularly in protic solvents. A protic solvent is one that has acidic protons, usually in the form of O—H or N—H groups. These groups form hydrogen bonds to negatively charged nucleophiles. Protic solvents, especially alcohols, are convenient solvents for nucleophilic substitutions because the reagents (alkyl halides, nucleophiles, etc.) tend to be quite soluble. [Pg.239]

Alkyl halides, as well as sulfonates, besides being useful for the preparation of derivatives as shown above, are widely utilized for the preparation of phosphorus derivatives such as R-PPhi Hal , precursors for the generation of Wittig reagents. Alkyl halides are also extremely important as intermediates in the preparation of the most valuable derivatives of oxidation level 0, the organometallic compounds. The required reduction step is usually carried out via direct reaction of the alkyl halides with an active metal such as lithium or magnesium. [Pg.103]

Deactivation against electrophilic attack accounts for the difficulty or failure of nitration, sulfonation and iV-oxidation of 1,2,4-triazoles proper. However, triazolate anions react readily with electrophilic reagents alkylation and acylation have received much attention but halogenation and addition reactions less. Systematic study of the formation and reactions of salts and metallic complexes is of recent origin. [Pg.744]

Via organometallic compounds (Grignard reagent). Alkyl halides react with either Mg or Li in dry... [Pg.56]

Both a- and t-NH2 groups are modified. Acyl derivatives of tyrosine formed by these reagents hydrolyze spontaneously under mild alkaline conditions. Small amounts of stable acyl derivatives of serine and threonine are formed. These can be quantitatively decomposed by treatment with 1 M NHjOH at pH 8.2 at 25°C for 2 hr. The olefmic reagents alkylate sulfhydryl groups with the formation of stable derivatives. [Pg.83]
